What was the thing that fixed this? And what release is the fix in? See https://community.kde.org/index.php?title=Guidelines_and_HOWTOs/Bug_triaging#General_considerations *** Bug 480577 has been marked as a duplicate of this bug. *** Apparently not fixed as we just got a duplicate report with the same backtrace. Re-opening. *** Bug 480754 has been marked as a duplicate of this bug. *** Let's call it fixed until it's not fixed *** Bug 490746 has been marked as a duplicate of this bug. *** Apparently not fixed again. Bug 490746 has some technical data that may be useful for debugging this. A possibly relevant merge request was started @ https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4553 I don't think the MR above is right, the point of the assert is to ensure that the output order is fully in sync with QGuiApplication::screens . By special casing the assert, we're just going to hit weirder bugs later. *** Bug 491102 has been marked as a duplicate of this bug. *** possible relevant commit: https://invent.kde.org/plasma/plasma-workspace/-/merge_requests/4642 This might have solved this, needs more testing The moentioned MR should fix this problem. if the problem persists after Plasma 6.2, please reopen this bug *** Bug 492420 has been marked as a duplicate of this bug. *** *** Bug 492730 has been marked as a duplicate of this bug. *** *** Bug 493130 has been marked as a duplicate of this bug. *** *** Bug 490746 has been marked as a duplicate of this bug. *** |
